CEILING-ROSE.

Lacasse.

To all whom t may concern Be it known that I, EDGAR IsoN PAnKns, a subject of the King of Great Britain, residing at Waterslade, Bushey Hall Road,

l-Bushey, in the county of Herts, and formerlyv of ldolholme, Lancaster Road, New Barnet, in the county of Hertford England, have invented new and useful lmprovements in Ceiling-Roses, of which the following is a specification. 1 Y

This invention relates to ceiling roses. Its purposes is to'provide a sound mechanical construction of rose which shall have the advantage of convenience in use.

It is a particular object of the invention to produce a ceiling rose from Vwhich theterminals may be removed for attachment of the conductors, and in which no -mechanical stress shall be taken by the electrical connections nor by the cover.

lt is also a purpose of the invention to avoid altogether the use of'screws passing into insulating material and generally to se# cure adequate insulation of the metal parts of opposite polarity. More particularly defined the invention comprises a ceiling rose having plugA and socket or other conveniently removable teri minal blocks, slid int-o recesses in the insula-ting base, said base having also formed upon it a cord grip to take the weight of the fitting.

These and further meritorious features of the invention will appear more clearly hereinafter and will be particularly delimited in the appended claims. Y

In the accompanying drawings which show a preferred construction of the invention Figure 1 is a plan of the ceiling rose with the cover removed, and Fig. 2 is an elevation with the cover in section.

From Fig. 1 it may be seen that the porcelain base 1 is formed with two upstanding ribs 2, 3, at right angles to one another. The rib 3 serves to separate and insulate from each other the metal parts of opposite polarity. The rib 2 has two square holes through it close against either side of the rib 3. Each of these receive a short metal bar or block 4 of square section. From one end of the block there extends into it a longitudinal hole 5 and at the other end is a transverse hole 6. This latter serves to place by the screw 7. The longitudinal hole Specification of Letters Patent.

5 receives'a split pin 8 which may be of ordinary form. verse perforation 9 in which the flexible conductor may be secured by the screw 10. At the' back of the base the openings 11 for thepassage of the circuit wires are preferably ccned as seen in Fig. 2. The endsof the rib 2 are notched on the upper surface and atvthe side as indicated at 12, 13, and it will be noted that the ends of the rib are in close proximity to the cover 14k.

rThe article may be used as follows. yThe plug 8 is withdrawn from the socket. The socket wire is put throughv hole 6 and clamped by screw 7 the socket and the channel in the base being non-circular, the former cannot turn as the screw is tightened. The ieXible conductors are then fastened in the holes 9 of the plugs 8'-.which obviously may be done on thev floor or at the workshop-and the plugs are pressed home into the sockets..

` may be formed in the porcelain. These en-Y gage between the head of the screw 7 and the block 4 as indicated, and the head of the screw is enlarged so that the block cannot be withdrawn unless the screw is first taken out.

bviously the ceiling rose may have more than two terminals according to the purpose it is to serve. They may be arranged in quite similar manner each with an insulating rib separating it from the next.

It is to be noted that as there are no lscrews screwing into the insulating material inthe rose, if the latter is of porcelain the whole may be glazed and then at no point can the metal terminals come into contact f with unglazed porcelain.

What I claim is:- 1. In a ceiling rose or like fitting, the

l Patented Nov. "2', 191 t?.

Application led October'ZG, 1911. Serial No. 656,931.

This pin has also a transv combination of'an insulating base, a cord f grip integral therewith, circuit terminals slidably mounted in and supported by said base, and lamp terminals carried by and slidably mounted in said circuit terminals. l 2. In a ceiling rose the combination of an insulating base, an insulating rib in- .tegral with said base and upstanding therefrom, terminals slidably mounted in said rib, a cord grip on said rib and a transverse imi Y rib on said base separating the terminals of opposite polarity. n Y

3. ln ceiling rose, the combination of an insulating base, two upstanding ribs .on

said base arranged to form a cross, one of said ribs having a pair of non-circular holes one on either side of the other rib, a pair of metal blocks each passing through one Vof said holes, means for connecting one of the Y maiirwi'res to each oi Ysaid metal blocks, a

pair of plugs one fitting into each of said metal blocks and means for connecting the flexible wires tovsaid plugs.

et. in a'ceiliiig'rose, the combination of an insulating base, an insulated rib upstand-Y to said pierced rib and at right angles to Ythe direction of sliding of said metal blocks and located to taketlie thrust of each of the metal blocks when said plugs are inserted and to prevent removal of said metal blocks I without removal oi" said terminal screws.

ln faceiliiig' rose, the combination of an insulating base, a perforated insulating rib upstanding therefrom, metal sockets passi ig through the perforations in said :Copies of this patent may be obtained for ribs, means for securing circuit wires to said sockets, metal plugs sliding in and making electric connection with said sockets, and means for securing lamp Wires to said plugs.

6. In a ceiling rose, the combination of a slotted insulating base, recessed terminal blocks for the main wires non-circular in section fitting in and 4freely slidable in said base, terminal screws in said blocks coaxial therewith and terminals for the lamp wires freely slidable in the `terminals for the main wires. Y y

7. In a ceiling rose vthe combination of an insulating base, a cord grip integral therewith, recessed circuit terminals slidab'ly mounted "in said base, l-amp terminals fitting in said circuit terminals, and upstandi-ng ribs in said base in the vpath vof movement of said circuit terminals.

8. In a ceilingY rose, the combination of an insulating base, terminal blocks slidable in said base, a rib integral with said base and adjacent -to the .ends of said blocks when the latter are in position, and terminal screws in said blocks but .passing loosely over said rib and having'heads too large to pass over said rib. Y

ln testimony whereof 'I have signed my name to this speciiication in the presence of two subscribing-witnesses.
